架构环境准备

模版机优化：

1.修改yum源为阿里云

rm -f /etc/yum.repos.d/*.repo

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

2.安装常用工具包

yum install net-tools vim tree htop iftop iotop lrzsz sl wget unzip telnet nmap nc psmisc dos2unix bash-completion sysstat rsync nfs-utils -y

3.关闭firewalld防火墙

systemctl disable firewalld

4.关闭selinux

sed -i '/^SELINUX=/c SELINUX=disabled' /etc/selinux/config

5.关闭networkmanager

6.更改主机名

hostnamectl set-hostname

7.小功能优化-优化系统提示符

echo "PS1='\[\e[32;1m\][\u@\h \W]\\$ \[\e[0m\]'" >>/etc/profile

source /etc/profile
